Grasshopper Escapement Clock

Long time no post. Pics show a clock based on a grasshopper escapement. All CAD work for the design was done using Vcarve pro.

Nice!
What was the smallest diameter bit that you used?

1.5mm dia for the gears and the escapement. The hour hand train is quite fine pitch and needed a small bit but the main train could have been done with 3mm.

Hello pcstru,

your clock is really fantastic. Is it your own design?
Do you sell the plans / files?
How difficult would it be for a newbie to make this clock?

regards
Rainer

Thanks. Yes it's my own design although I'm indebted to jltrent of the beall tool clockforum who produced a software tool which calculates the geometry for the grasshopper escapement and gear profiles available here.

The plans are just laid out in vcarve pro, there is no detail on assembly or any of the other nice things you should get with bought plans, so at the moment I don't anticipate selling them although I may tidy them up a bit and open source them. Given a CNC machine, clocks aren't difficult to make. David Atkinson has some good plans for sale at http://www.woodentimes.com/. They come with detailed assembly instructions and the components laid out in DXF format - easy to import into Vcarve pro. If you fancy building a clock, that would be a good place to start. The 'god' of wooden clocks is probably a chap called Clayton Bower. He sells a large number of plans on his site http://www.lisaboyer.com/Claytonsite/Claytonsite1.htm. I'm not sure if they come as DXF files though.

Amazing work! I have always wanted to build a wooden clock.

If you do decide to put your design up for sale count me in!
